Could not agree more. I know the thoery but the practice it's a whole 
different ball park.

Took me sometime to figure this one out. But it's not solder but 
tinned. And the process is called pattern plating.

As a homebrewer it is too expensive for me to send boards out to 
make. If I could only find out a simple way to make plated thru holes 
at home without killing myself. And eyelets and baluns are too time 
consuming.
